ABSTRACT
Purpose To evaluate the influence of autonomic vagal and splenic activities on renal histomorphometric aspects in obese rats. Methods Thirty male Wistar rats were used, of which, 24 received subcutaneous injections of monosodium glutamate (MSG) during the first 5 days of life (4 g/kg body weight) and six control animals received injections of saline solution (CON). Five experimental groups were organized (n = 6/group) falsely-operated control (CON-FO); falsely-operated obese (MSG-FO); vagotomized obese (MSG-VAG); splenectomized obese (MSG-SPL); vagotomized and splenectomized obese (MSG-VAG-SPL). Results The MSG-FO group animals showed a significant reduction in body weight and nasal-anal length when compared to CON-FO group animals (p 0.05). The MSG-VAG-SPL group showed significant reduced in most biometric parameters associated with obesity. Falsely-operated obese animals showed a significant reduction in renal weight, glomerular diameters, glomerular tuff and capsule areas and Bowmans space compared to CON-FO group animals (p < 0.05). There was a significant reduction in diameter, glomerular tuft and capsule areas, and Bowmans space in MSG-VAG, MSG-SPL, MSG-VAG-SPL groups when compared to the MSG-FO group. Conclusions Vagotomy associated with splenectomy induces a reduction in the adiposity and causes histological changes in the kidney of obese rats.(AU)
